Thanks for posting this question in HCM Let me tell you that headache could be due to various reason jsut like fever can happen due to vatious reasons. Headache can be due to migraine, cluster headache, brain tumor, brain infection, problemsd related to blood vessels of the brain. Headcahe can also be due to medicines, flu etc. The history you have given could be the onset of migraine. But one has to clearly remember that you have only one such episode and migraine is a dianosis of exclusion. What i mean is that we can stamp somebody as haveing migraine when we rule out the secondary causes which can mimic like migrain as i have listed above. You may follow the following two paths. 1. Get examined by a neurologist and he will tell you if there is any clinical neurological deficit which will guide us for getting a brain scan (to rule out the other causes as i have detailed above). If both the examinations and scans are normal, then you can try simple analgesics like paracetamol and avoid lights proloned work with lap top and may use dark glasses to avoid visual sensitivity 2. In the absence of other neurological symptoms you can try things which i have told in point o 1 above and observe and report to a neurologist if you develop new symptoms or persistence of the curent problems. Hope this clarifies
